Definitions

  • the present invention relates to a steel laminate gasket with a plate information device so that a kind of gasket is readily recognized after the gasket is assembled.
  • the gasket is formed of a plurality of steel plates. Since the outer configuration is substantially the same in all the steel plates, it is very difficult to recognize the plates after assembly.
  • a top clearance between a piston at a top dead center and an inner top portion of a cylinder head is precisely selected, because the top clearance affects the power and exhaust gas of an engine.
  • the top clearance is generally determined when an engine is designed. However, since a gasket is installed between a cylinder head and a cylinder block, a precise adjustment of the top clearance is made by selecting the thickness of the gasket.
  • the same engines are used for different models of cars.
  • the engines are slightly modified to suit the respective models.
  • the top clearance may be changed by changing the thickness of a gasket.
  • one of plates is exchanged for a different plate with different thickness. Namely, in the same gasket, a plurality of plates with different thickness is prepared and used according to the models of the cars.
  • the respective plates must have projections to identify the plates. Namely, even if the configuration of the plates is the same, since the respective plates have different projections, different cutting devices are required for cutting the respective plates. Therefore, this method is not proper in case at least one plate in a steel laminate gasket is to be identified.
  • one object of the invention is to provide a steel laminate gasket, wherein a steel plate situated in a middle of a gasket can be easily identified after the gasket is assembled.
  • Another object of the invention is to provide a steel laminate gasket as stated above, wherein all the plates can be manufactured by the same cutting device without using a different cutting device.
  • a further object of the invention is to provide a steel laminate gasket as stated above, which can be manufactured easily and economically.
  • a steel laminate gasket to be installed between two engine parts is provided with a plate information device.
  • the gasket comprises at least one first metal plate for constituting the steel laminate gasket and at least one second metal plate stacked with the first metal plate.
  • the size of the first plate is substantially the same as that of the engine parts, and the first plate is provided with a plate information area inside the first plate.
  • the second metal plate is provided with a plate information sign at an area corresponding to the plate information area of the first plate. Therefore, after the first and second metal plates are assembled, the plate information sign of the second metal plate is seen through the plate information area of the first plate.
  • the plate information area of the first plate may be a hole or a notch. Therefore, the plate information area does not project outside the engine parts.
  • FIG. 1 is a plan view of a steel laminate gasket with a plate information device of the invention
  • FIG. 2 is an enlarged perspective view for showing the plate information device
  • FIGS. 3A and 3B are explanatory plan views for showing different embodiments of the plate information device.
  • FIG. 4 is an explanatory plan view for showing a still different embodiment of the plate information device.
  • FIGS. 1 and 2 a first embodiment A of a steel laminate gasket of the invention is shown.
  • the gasket A is a water holes Hw, push rod holes Hp and so on, as in the conventional gasket.
  • Sealing devices are formed around the cylinder holes Hc, water holes Hw and push rod holes Hp.
  • the sealing devices are not shown in the drawings. Any kind of sealing devices may be used.
  • the gasket A comprises an upper plate 10, middle plates 12, 14 and a lower plate 16.
  • the outer configuration of the plates 10, 12, 14, 16 is substantially the same as a cylinder head and a cylinder block (both not shown). Therefore, nothing projects outwardly from the cylinder head and cylinder block when the gasket A is installed thereto.
  • the plates 10, 12, 16, have notches 10a, 12a, 16a at their side portions where sealing ability of the gasket A is not affected.
  • the notches 10a, 12a, 16a align vertically.
  • the plate 14 is provided with two dents 14a, which are located at an area where the notches 10a, 12a, 16a are positioned when the gasket A is assembled.
  • the dents 14a constitute signs for the plate 14. Therefore, even after the plates are assembled, the dents 14a of the plate 14 can be seen through the notches 10a, 12a or notch 16a.
  • the plate 14 is a plate for adjusting the thickness of the gasket A. Therefore, when the thickness of the gasket A is changed, the plate 14 is replaced by a different plate with different sign. The sign can be seen through the notches of the plates 10, 12, 16.
  • FIGS. 3A and 3B are explanatory plan views of the embodiments B and C of the present invention.
  • plates B10, B12, B16 plates B10, B12, B16 are not shown), which are the same as the plates 10, 12, 16, are used.
  • the plate B14 situated between the plates B12, B16 is different in thickness from the plate 14, so that the plate B14 does not have any dent.
  • the plate B14 can be seen through a notch B10a. As a result, the difference of the gaskets A, B can be easily recognized.
  • a plate C14 with a dent C14a is used instead of a plate 14 in the gasket A.
  • the dent C14a can be seen through a notch C10a of a plate C10.
  • FIG. 4 shows a fourth embodiment D of a steel laminate gasket of the invention, wherein plates D10, D12, D16 (D12, D16 are not shown) similar to the plates 10, 12, 16 have elongated holes D10a, D12a, D16a (D12a, D16a are not shown) instead of the notches.
  • a plate D14 has two holes D14a at an area corresponding to the elongated holes D10a, D12a, D16a. Therefore, the holes D14a can be seen through the elongated holes. Even if the elongated holes are formed instead of the notches, the gasket D operates as in the gasket A.
  • a plate which may be changed when the thickness of a gasket is altered is provided with a plate information sign, and the other plates are provided with notches or holes so that the plate information sign can be seen from the notches or holes. Therefore, when the plates are assembled, the plate with the plate information sign can be seen to identify the gasket.
  • notches or holes are formed inside the plate. Namely, none of the portions projects outwardly when the gasket is installed in an engine. Therefore, the gasket does not hinder installation of other parts of a car.
  • the plates have the same outer configuration possible to use the same cutting device for cutting the plates. Pins for cutting the holes or notches may be attached to the cutting device when required. As a result, the gasket can be manufactured economically.
